I've got a user who would like to search across her calendar and calendars she is a delegate for at the same time. However it doesn't appear that this is a feature that is support in O365 when combined with Outlook 2010.

Sorry there seems to be confusing about what I'm asking, I know how to give people calendar delegate access, that's not the issue.

I'm specifically referring to searching across multiple calendars at the same time, when those multiple calendars include calendars that they are a delegate for. So as an example, User A has access to the following calendars....

User A

Boardroom

Meeting Room

User B

User C

If they do a search in the Calendar section of their Outlook for a term that they know is in all 5 calendars, results are only returned for items in the calendars or User A, Boardroom, and Meeting Room.

Items in User B and User C are not displayed in the search results.

Is this a feature of O365 or Outlook 2010? Is there a way around this?
